Not sure if anyone has read this very interesting article explaining the relationship. My depressive periods are definately ''atypical'' i.e. leaden type paralysis, rejection sensitivity and mood improving once getting into work or mingling with folk.

The analysis here is that those diagnosed Borderline generally have atypical features to their depression and according to the study here 70% of them would meet the criteria for Bipolar II with an even higher number considered to be on the bipolar spectrum.

It is a bit of a nightmare I think for someone to be told by two different pdocs that you have two conditions which both involve extremes of thinking and mood. I suppose I must just have faith in trusting them to have got it right. It would really affect me having to be arguing the toss again about diagnosis/treatment when I spent 5 years or more putting off seeing a psychiatrist when my doctor suggested I could be bipolar.
